Our Process

sheet metal ductwork fabrication

Fabrication – Fabricating your sheet metal HVAC ductwork is one of the most important steps of the process. Not only can we fabricate high quality air ducts, but we can also fabricate any custom order that you may need such as metal panels, drain pans, machine guards, cupola covers, steel frames, and much more. If you can sketch it, we can make it. We fabricate all ducts to SMACNA standards using the highest quality sheet metal materials and best industry standards.

Ductwork Installation – Our craftsmen will install your sheet metal ducts correctly the first time and on schedule. When the system is installed it will be tested and adjusted to ensure it is functioning properly.

Repairs – Our experienced craftsmen can perform repairs on all duct systems and all metal types.

Please feel free to contact us if you have any questions about sheet metal fabrication for a new HVAC system or for repairs of your existing system today.

Frequently asked questions

What makes RC Metalworks different from other sheet metal fabricators?
RC Metalworks combines craftsmanship, precision, and deep HVAC expertise. All of our ductwork is fabricated to SMACNA standards using high-quality metals, and every piece is custom-built with accuracy in mind. We work with a wide range of industries so we understand the performance demands of complex environments. Whether you need standard ductwork or custom metal components, we deliver solutions built to last and completed on schedule.
Can you help determine whether my current duct system needs repair or full replacement?
Yes. Our experienced craftsmen can evaluate your existing system, identify performance issues, and recommend the most cost-effective solution. In many cases, targeted repairs are all that’s needed. Other systems may benefit from partial or full replacement to improve efficiency, airflow, or code compliance. We provide clear recommendations so you can make an informed decision.
What materials do you recommend for my HVAC system?
We fabricate ductwork and custom components from galvanized steel, aluminum, stainless steel, black iron, copper, and lead-coated copper. The best material depends on your system’s environment, airflow requirements, and durability needs. We’ll review your project and recommend the most appropriate and cost-effective material.
Can you work around business hours to minimize disruption?
Absolutely. Many of our clients - including hospitals, universities, and commercial facilities - require work during off-hours or phased schedules. We can coordinate installation or repairs around your operating hours to ensure minimal impact on staff, customers, or building occupants.
What quality checks or testing do you perform during final installation?
Before any project is completed, we perform a full review of fabrication quality, proper sealing, system fit, and overall structural integrity. After installation, we test and adjust airflow to confirm the ductwork is functioning correctly within your HVAC system. These checks ensure long-term performance and help you avoid costly issues down the road.
